There is a lot involved that a child must due to serve themselves snack and beaware that their must be enough for everyone to eat.
Practing counting, matching object to outline, one to one corespondence.
Mumble was able to recognize his name.
Once most of the children are able to recognize their names the whole snack routine will be less of me and more of them. For now I will be pairing up children with one who does know their name. That way since there are only two chairs the child will be able to use process of elimination. They all have shown me that they know how to do this by playing musical chairs.
